Question about Sears Craftsman LiftMaster Chamberlain Garage Door Opener Wireless Keypad Model 976LM Security+

1 Answer

When try to use remotes or wall control to close garage door, lights blink 8 times. Can only close by holding down wall control the entire way.

    I'm having the same problem as NWallace from May 17. My craftsman 1/2 hp garage door will only close if I hold the wall control down the entire time it is closing (and the light blinks the entire time). I think I have muliptle problems.

    1. Only one door sensor lights up (and no matter how I adjust it, I can't get the second to light up).

    2. The remote doesn't do anything. I replaced the batteries, and tried to reprogram several times, but still nothing. I'm considering buying a new remote.

    My question is, shouldn't the remote work like the wall control (even if the sensors are screwed up - thus holding button down entire time on remote would open door with it too)? Or, must the door sensors be fixed before the remote will work.

    Second question, the instructions on the garage door unit itself to reprogram the remote are different than the ones on the instructions on the remote itself? Why is that? Which should I use? (Neither has worked so far).

    Anyway, any advice would be appreciated.

    Thanks,

    Ray - Arizona

Your door sensors are most likely misaligned. Each of them should have a small light that is lit and not blinking. Tweak them until both are lit.

It could be the garage door motor that is acting up. Try closing it with the button in the garage. If that's not the case, you may need a different garage door opener.

The only thing that will cause the main light to flash 10 times and the door to reverse to the open position is a sensor problem. Make sure the light on each sensor is on and not flickering ever so slightly. Make sure they are not moving when the door starts to close. Lights on sensors should not blink. One light should stay on constantly and the other sensors light should go off when you block the sensors.

The green light on the wall switch is blinking constantly yet it works to open/close the door. The remote does not work. Any suggestions?


Press and hold the lock button on the wall control for 3 seconds. The light will stop blinking and your remotes will work.

No reponse when using the remote, the wall control works fine.


The remotes use a receiver to actuate the door and the wall control does not. It sounds like your logic board is bad. Maybe a lightning storm recently? Try removing the board and look for burnt or missing traces on the printed circuit.

Door won't close, with out hold down on button.


If the main light flashes 10 times when the door reverses it is a door sensor problem. Make sure they are pointed at one another and the small light on each one is lit and not blinking.

Garage door wont work with remote


If the small light in your wall control is blinking it is in the lock mode. Press and hold for 3 seconds the button with the icon of a lock. This will toggle the lock function off.

I have to hold down the wall mounted opener the entire time that the door is closing. The remote will not close the door. They both open the door fine.


Look at the back of the opener, the LED light blinks. Count how many blinks, then go to the troubleshooting guide to find the fault.
